AMD Goes Virtual With Liquid VR
AMD Liquid VR is not a retail product – it is an initiative to develop and deliver the best Virtual Reality (VR) experience in the industry.
AMD Liquid VR was announced at the Game Developers Conference in San Francisco, and the company describes it is a “set of innovative technologies focused on enabling exceptional VR content development” for hardware based on AMD silicon.
Developers will soon get access to the LiquidVR SDK, which will help them address numerous issues associated with VR development.
Platform and software rather than hardware
If you were expecting to see a sexy AMD VR headset with a killer spec, the announcement may be disappointing. However, if you are a “what’s under the bonnet” kind of geek, there are a few interesting highlights.
AMD has put a lot of effort into minimising motion-to-photon latency, which should not only help improve the experience, but also keep you from experiencing motion sickness, or hurling over that new carpet that really ties the room together.
Headline features of LiquidVR SDK 1.0 include:
Async Shaders for smooth head-tracking enabling Hardware-Accelerated Time Warp, a technology that uses updated information on a user’s head position after a frame has been rendered and then warps the image to reflect the new viewpoint just before sending it to a VR headset, effectively minimizing latency between when a user turns their head and what appears on screen.
Affinity Multi-GPU for scalable rendering, a technology that allows multiple GPUs to work together to improve frame rates in VR applications by allowing them to assign work to run on specific GPUs. Each GPU renders the viewpoint from one eye, and then composites the outputs into a single stereo 3D image. With this technology, multi-GPU configurations become ideal for high performance VR rendering, delivering high frame rates for a smoother experience.
Latest data latch for smooth head-tracking, a programming mechanism that helps get head tracking data from the head-mounted display to the GPU as quickly as possible by binding data as close to real-time as possible, practically eliminating any API overhead and removing latency.
Direct-to-display for intuitively attaching VR headsets, to deliver a seamless plug-and-play virtual reality experience from an AMD Radeon™ graphics card to a connected VR headset, while enabling features such as booting directly to the display or using extended display features within Windows.

What’s next for LiquidVR?
It all depends on what you were expecting, and what the rest of the industry does. AMD hopes LiquidVR will be compatible with a broad range of VR devices. LiquidVR will allow hardware makers to implement AMD technology in their products with relative ease, enabling 100Hz refresh rates, the use of individual GPUs per each eye and so on.
To a certain extent, you can think of LiquidVR as FreeSync for VR kit.
Oculus CEO Brendan Irbe said achieving presence in a virtual world is one of the most important elements needed to deliver a good user experience.
He explained where AMD comes in:
“We’re excited to have AMD working with us on their part of the latency equation, introducing support for new features like asynchronous timewarp and late latching, and compatibility improvements that ensure that Oculus’ users have a great experience on AMD hardware.”
Raja Koduri, corporate vice president, Visual Computing, AMD, said content, comfort and compatibility are the cornerstones of AMD’s focus on VR.
AMD’s resident graphics guru said:
“With LiquidVR we’re collaborating with the ecosystem to unlock solutions to some of the toughest challenges in VR and giving the keys to developers of VR content so that they can bring exceptional new experiences to life.”
A picture is worth a thousand words, so here’s 3300 frames of AMD’s virtual reality vision.
Can MediaTek Take On Qualcomm?
While Qualcomm’s 20nm Snapdragon 810 SoC might be the star of upcoming flagship smartphones, it appears that MediaTek has its own horse for the race, the octa-core MT6795.
Spotted by GforGames site, in a GeekBench test results and running inside an unknown smartphone, MediaTek’s MT6795 managed to score 886 points in the single-core test and 4536 points in the multi-core test. These results were enough to put it neck to neck with the mighty Qualcomm Snapdragon 810 SoC tested in the LG G Flex 2, which scored 1144 points in the single-core and 4345 in the multi-core test. While it did outrun the MT6795 in the single-core test, the multi-core test was clearly not kind on the Snapdragon 810.
The unknown device was running on Android Lollipop OS and packed 3GB of RAM, which might gave the MT6795 an edge over the LG G Flex 2.
MediaTek’s octa-core MT6795 was announced last year and while we are yet to see some of the first design wins, recent rumors suggested that it could be powering Meizu’s MX5, HTC’s Desire A55 and some other high-end smartphones. The MediaTek MT6795 is a 64-bit octa-core SoC clocked at up to 2.2GHz, with four Cortex-A57 cores and four Cortex-A53 cores. It packs PowerVR G6200 graphics, supports LPDDR3 memory and can handle 2K displays at up to 120Hz.
As we are just a few days from Mobile World Congress (MWC) 2015 which will kick off in Barcelona on March 2nd, we are quite sure that we will see more info as well as more benchmarks as a single benchmark running on an unknown smartphone might not be the best representation of performance, it does show that MediaTek certainly has a good chip and can compete with Qualcomm and Samsung.
AMD Headed To The Facial Recognition Space
Comments Off on AMD Headed To The Facial Recognition Space
AMD has developed facial recognition technology to enable users to organize and search video clips based on the people featured in them.
AMD executive Richard Gayle demonstrated to Tom’s Guide how AMD Content Manager, uses facial recognition to browse through a group of local videos to find specific faces.
There is an index that displays the people’s faces that have been detected throughout the video clips.
The user can edit the names of the people as well as add keyword tags to help improve future searches for specific people.
For instance, if you are searching for videos that feature one person, you can click on his or her respective face to pull up the corresponding videos.
Additionally, if you want to narrow a search to a specific person combined with a keyword tag, you can drag the face icon and click on the desired keyword.
Once you click on the video you wish to view, a player appears in the right windowpane, along with a timeline displayed at the bottom with a list of all the people who appear in the video.
The timeline is separated into various coloured boxes to mark the exact moment in the video when each person first appears on screen, so you do not have to watch the entire video to see the bit you want.
The application also has facial recognition capabilities that allow users to do some basic editing, such as compiling a single montage video of any individual or individuals.
While this is pretty good technology, it probably does not have any major use yet on its own.
Gayle said it is unlikely that AMD will release Content Manager in its current form but will license it to OEMs that are able to rebrand the application before offering it on their respective systems.
He claimed that only AMD processors have sufficient power to operate the application, because of the processor’s ability to have the CPU, GPU and memory controller work closely together.
AMD’s Fiji GPU Goes High Bandwidth
New evidence coming from two LinkedIn profiles of AMD employees suggest that AMD’s upcoming Radeon R9 380X graphics card which is expected to be based on the Fiji GPU will actually use High-Bandwidth Memory.
Spotted by a member of 3D Center forums, the two LinkedIn profiles mention both the R9 380X by name as well as describe it as the world’s firts 300W 2.5D discrete GPU SoC using stacked die High-Bandwidth Memory and silicon interposer. While the source of the leak is quite strange, these are more reliable than just rumors.
The first in line is the profile of Ilana Shternshain, an ASIC Physical Design Engineer, which has been behind the Playstation 4 SoC, Radeon R9 290X and R9 380X, which is described as the “largest in ‘King of the hill’ line of products.”
The second LinkedIn profile is the one from AMD’s System Architect Manager, Linglan Zhang, which was involved in developing “the world’s first 300W 2.5D discrete GPU SOC using stacked die High Bandwidth Memory and silicon interposer.”
Earlier rumors suggest that AMD might launch the new graphics cards early this year as the company is under heavy pressure from Nvidia’s recently released, as well as the upcoming, Maxwell-based graphics cards.
nVidia Finally Goes 20nm
For much of the year we were under the impression that the second generation Maxwell will end up as a 20nm chip.
First-generation Maxwell ended up being branded as Geforce GTX 750 and GTX 750 TI and the second generation Maxwell launched a few days ago as the GTX 980 and Geforce GTX 970, with both cards based on the 28nm GM204 GPU.
This is actually quite good news as it turns out that Nvidia managed to optimize power and performance of the chip and make it one of the most efficient chips manufactured in 28nm.
Nvidia 20nm chips coming in 2015
Still, people keep asking about the transition to 20nm and it turns out that the first 20nm chip from Nvidia in 20nm will be a mobile SoC.
The first Nvidia 20nm chip will be a mobile part, most likely Erista a successor of Parker (Tegra K1).
Our sources didn’t mention the exact codename, but it turns out that Nvidia wants to launch a mobile chip first and then it plans to expand into 20nm with graphics.
Unfortunately we don’t have any specifics to report.
AMD 20nm SoC in 2015
AMD is doing the same thing as its first 20nm chip, codenamed Nolan, is an entry level APU targeting tablet and detachable markets.
There is a strong possibility that Apple and Qualcomm simply bought a lot of 20nm capacity for their mobile modem chips and what was left was simply too expensive to make economic sense for big GPUs.
20nm will drive the voltage down while it will allow higher clocks, more transistors per square millimeter and it will overall enable better chips.
Just remember Nvidia world’s first quad-core Tegra 3 in 40nm was rather hot and making a quad core in 28nm enabled higher performance and significantly better battery life. The same was true of other mobile chips of the era.
We expect similar leap from going down to 20nm in 2015 and Erista might be the first chip to make it to 20nm. A Maxwell derived architecture 20nm will deliver even more efficiency. Needless to say AMD plans to launch 20nm GPUs next year as well.
It looks like Nvidia’s 16nm FinFET Parker processor, based on the Denver CPU architecture and Maxwell graphics won’t appear before 2016.
GPUs Down In Q1

Comments Off on GPUs Down In Q1
According to Jon Peddie Research (JPR), shipments of discrete graphics cards were down in the first quarter of the year. This is in line with seasonal trends, as the market cools down after the holiday season.
The sequential drop was 6.7 percent, which was still better than the overall desktop PC market, which slumped 9 percent. However, on a year-to-year basis add-in-board (AIB) shipments were down 0.8 percent. PC sales were down 1.1 percent.
Nvidia still controls two thirds of the market
Total AIB shipments in Q1 were just 14 million units. AMD and Nvidia both saw their shipments decrease 6.6 percent, so their market share did not change much.
Nvidia controls an estimated 65 percent of the market, up from 64.2 percent last year. AMD’s market share in Q1 was 35 percent, down from 35.6 percent a year ago.
The overall volume remains weak and in the long run things could get even worse, as on-die integrated graphics have already taken a big toll on sales of entry level discrete cards. As integrated GPUs become even faster, they are likely to cannibalize the low end market even further.
JPR points out that the AIB market peaked in 1999, with 114 million units shipped. Last year saw only 65 million units and the stagnant trend is likely to continue this year.
It’s not all bad news for AIBs
Although the slump in discrete GPU shipments is hurting AMD and NV hardware partners, JPR offers a rather encouraging outlook.
It points out that graphics cards are one of the most powerful, essential and exciting components in the PC market today. PC gaming is hardly dead, in fact it is going through what can only be described as a small renaissance. PCs will offer 4K/UHD gaming years ahead of consoles and the Steam Machine concept is looking good, too.
The compute market is another driver, as JPR points out:
“The technology is entering into major new markets like supercomputers, remote workstations, and simulators almost on a daily basis. It would be little exaggeration to say that the AIB resembles the 800-pound gorilla in the room.”
The AIB market is quite a bit less colourful and eventful than it was back in the day, but at least AIBs still have a lot on their hands and they are trying to tap new markets.
Can AMD Grow
AMD posted some rather encouraging Q1 numbers last night, but slow PC sales are still hurting the company, along with the rest of the sector.
When asked about the PC market slump, AMD CEO Rory Read confirmed that the PC market was down sequentially 7 percent. This was a bit better than the company predicted, as the original forecast was that the PC market would decline 7 to 10 percent.
Rory pointed out that AMD can grow in the PC market as there is a lot of ground that can be taken from the competition. The commercial market did better than expected and Rory claims that AMD’s diversification strategy is taking off. AMD is trying to win market share in desktop and commercial segments, hence AMD sees an opportunity to grown PC revenue in the coming quarters. Rory also expects that tablets will continue to cannibalize the PC market. This is not going to change soon.
Kaveri and Kabini will definitely help this effort as both are solid parts priced quite aggressively. Kabini is also available in AMD’s new AM1 platform and we believe it is an interesting concept with plenty of mass market potential. Desktop and Notebook ASPs are flat which is something that the financial community really appreciated. It would not be so unusual that average selling prices were down since the global PC market was down.
Kaveri did well in the desktop high-end market in Q1 2014 and there will be some interesting announcements in the mobile market in Q2 2014 and beyond.
AMD, Intel & nVidia Go OpenGL
AMD, Intel and Nvidia teamed up to tout the advantages of the OpenGL multi-platform application programming interface (API) at this year’s Game Developers Conference (GDC).
Sharing a stage at the event in San Francisco, the three major chip designers explained how, with a little tuning, OpenGL can offer developers between seven and 15 times better performance as opposed to the more widely recognised increases of 1.3 times.
AMD manager of software development Graham Sellers, Intel graphics software engineer Tim Foley and Nvidia OpenGL engineer Cass Everitt and senior software engineer John McDonald presented their OpenGL techniques on real-world devices to demonstrate how these techniques are suitable for use across multiple platforms.
During the presentation, Intel’s Foley talked up three techniques that can help OpenGL increase performance and reduce driver overhead: persistent-mapped buffers for faster streaming of dynamic geometry, integrating Multidrawindirect (MDI) for faster submission of many draw calls, and packing 2D textures into arrays, so texture changes no longer break batches.
They also mentioned during their presentation that with proper implementations of these high-level OpenGL techniques, driver overhead could be reduced to almost zero. This is something that Nvidia’s software engineers have already claimed is impossible with Direct3D and only possible with OpenGL (see video below).
Nvidia’s VP of game content and technology, Ashu Rege, blogged his account of the GDC joint session on the Nvidia blog.
“The techniques presented apply to all major vendors and are suitable for use across multiple platforms,” Rege wrote.
“OpenGL can cut through the driver overhead that has been a frustrating reality for game developers since the beginning of the PC game industry. On desktop systems, driver overhead can decrease frame rate. On mobile devices, however, driver overhead is even more insidious, robbing both battery life and frame rate.”
The slides from the talk, entitled Approaching Zero Driver Overhead, are embedded below.
At the Game Developers Conference (GDC), Microsoft also unveiled the latest version of its graphics API, Directx 12, with Direct3D 12 for more efficient gaming.
Showing off the new Directx 12 API during a demo of Xbox One racing game Forza 5 running on a PC with an Nvidia Geforce Titan Black graphics card, Microsoft said Directx 12 gives applications the ability to directly manage resources to perform synchronisation. As a result, developers of advanced applications can control the GPU to develop games that run more efficiently.
Is AMD Worried?
AMD’s Mantle has been a hot topic for quite some time and despite its delayed birth, it has finally came delivered performance in Battlefield 4. Microsoft is not sleeping it has its own answer to Mantle that we mentioned here.
Oddly enough we heard some industry people calling it DirectX 12 or DirectX Next but it looks like Microsoft is getting ready to finally update the next generation DirectX. From what we heard the next generation DirectX will fix some of the driver overhead problems that were addressed by Mantle, which is a good thing for the whole industry and of course gamers.
AMD got back to us officially stating that “AMD would like you to know that it supports and celebrates a direction for game development that is aligned with AMD’s vision of lower-level, ‘closer to the metal’ graphics APIs for PC gaming. While industry experts expect this to take some time, developers can immediately leverage efficient API design using Mantle. “
AMD also told us that we can expect some information about this at the Game Developers Conference that starts on March 17th, or in less than two weeks from now.
We have a feeling that Microsoft is finally ready to talk about DirectX Next, DirectX 11.X, DirectX 12 or whatever they end up calling it, and we would not be surprised to see Nvidia 20nm Maxwell chips to support this API, as well as future GPUs from AMD, possibly again 20nm parts.
AMD’s Richland Shows Up
Kaveri is coming in a few months, but before it ships AMD will apparently spice up the Richland line-up with a few low-power parts.
CPU World has come across an interesting listing, which points to two new 45W chips, the A8-6500T and the A10-6700T. Both are quads with 4MB of cache. The A8-6500T is clocked at 2.1GHz and can hit 3.1GHz on Turbo, while the A10-6700T’s base clock is 2.5GHz and it maxes out at 3500MHz.
The prices are $108 and $155 for the A8 and A10 respectively, which doesn’t sound too bad although they are still significantly pricier than regular FM2 parts.
